The transmittance and absorption properties of certain soft-lens materials with a low and a high water content and a hard-lens material were analyzed by a spectrophotometric technique over a broad spectrum from ultraviolet (195 nm) to far infrared (40,000 nm) radiation. The dry lens materials not only showed marked absorption within the short-wave region of ultraviolet, but also very strong absorption within the infrared range, especially medium and far infrared. Wet soft-lens material showed greatly increased absorption within the infrared regions in which water shows absorption maximums. Therefore the wet soft-lens materials absorbed nearly 100% of the radiation within the greater part of the medium and far infrared ranges. Transmittance and absorption were inevitably affected by the thickness of the material, but differences between the various makes of lens were minor. It is clear that sources of high-energy radiation, particularly within the infrared spectra, may constitute hazards with regard to the absorption of radiation and the consequent generation of heat in contact lenses.
通过光谱光度技术，分析了具有低含水量和高含水量的软性隐形眼镜材料以及硬性隐形眼镜材料的透射率和吸收率，其辐射范围从紫外线（195nm）到远红外（40000nm）。干燥的隐形眼镜材料不仅在紫外线的短波区域表现出明显的吸收，而且在红外线区域也表现出很强的吸收，尤其是在中波和远红外线区域。湿软性隐形眼镜材料在水吸收最大值的红外线区域内显示出极大的吸收增加。因此，湿软性隐形眼镜材料在中波和远红外线的大部分区域内几乎吸收了 100%的辐射。透射率和吸收率不可避免地受到材料厚度的影响，但不同品牌的镜片之间差异较小。显然，高能辐射源，尤其是在红外线光谱范围内，可能会对隐形眼镜的辐射吸收和随之产生的热量构成危害。
